“…Results showed that within certain distance, IEEE802.11a and g based VANET are able to achieve better stability good put, while IEEE802.11b based VANET is better suited for long distance communication. On the other hand, a novel adaptation of PMIPv6 for multi-hop VANET scenarios is introduced in [44], to ensure efficient network mobility management. This shows the importance of network selection in VANET towards determining the transmission efficiency.…”

Cognitive radio network and Vehicular Ad hoc Network (VANET) are recent emerging concepts in wireless networking. Cognitive radio network obtains knowledge of its operational geographical environment to manage sharing of spectrum between primary and secondary users, while VANET shares emergency safety messages among vehicles to ensure safety of users on the road. Cognitive radio network is employed in VANET to ensure the efficient use of spectrum, as well as to support VANET's deployment. Random increase and decrease of spectrum users, unpredictable nature of VANET, high mobility, varying interference, security, packet scheduling and priority assignment are the challenges encountered in a typical cognitive VANET environment. This paper provides survey and critical analysis on different challenges of cognitive radio VANET, with discussion on the open issues, challenges and performance metrics, for different cognitive radio VANET applications.

“…Most of the existing works on mobility management [16,25] focus on layer-3 schemes to extend the support of Mobile IP (MIP) to vehicular networks but not on the handover decision parameters. The handover decision is mostly based on either of the RSSI [14] or LET [30,15] metric. To efficiently support the dissemination of high resolution and delay sensitive telescreen content in urban areas, we propose a handover decision mechanism based on both the RSSI and LET parameters to select a stable link and avoid unnecessary handovers.…”

Quality of service and mobility aware in-vehicle telescreen service architecture

Original scientific paper This paper presents an architecture for providing quality of service (QoS) and mobility-aware telescreen services in vehicular networks, named "in-vehicle telescreen" (IVT). Providing seamless imagery effect is a key challenge in the distribution of high-resolution and delay-sensitive infotainment IVT services under mobile and varying network conditions. In the IVT architecture, new functions of information and service quality management are introduced to manage the user registrations, service advertisements, network information, and service quality. We propose an adaptive selection of application QoS parameters and an IVT handover decision mechanism for providing seamless imagery effect and enhance user's multimedia perception. The proposed architecture can provide a sustainable channel rate based selection of content source, media resolution, and codec to improve the perceived visual quality. Furthermore, the paper presents a Link Expiration Time and Received Signal Strength Indicator based IVT handover decision mechanism that can minimize the number of handovers by selecting a stable path. An extensive simulation is performed to show the effectiveness of the proposed mechanisms. Keywords: handover decision mechanism; in-vehicle telescreen; quality-of-experience; quality-of-service; vehicular networks Arhitektura kvalitete usluge i usluge tele-ekrana u pokretnim voznim mrežamaIzvorni znanstveni članak U radu se predstavljena arhitektura za osiguranje kvalitete usluge (quality of service -QoS) i usluge tele-ekrana u voznim mrežama koje reagiraju na pokretljivost, nazvane teleekran unutar vozila -"in-vehicle telescreen" (IVT). Osiguranje nepromjenljive slike je ključni izazov u pružanju IVT usluga visoke rezolucije u mobilnim uvjetima i uvjetima variranja mreže. U IVT arhitekturi uvode se nove funkcije upravljanja kvalitetom informacija i usluga u vođenju registracije korisnika, oglašavanju usluga, obavijesti o mreži, i kvaliteti usluge. Predlažemo prilagodljiv izbor QoS parametara te mehanizam za donošenje odluke o prekapčanju IVT kako bi se osigurala čista slika i poboljšala multimedijska percepcija korisnika. Predloženom se arhitekturom može osigurati izbor izvora sadržaja zasnovan na prosječnoj kanalskoj brzini, rezolucija medija i kodek (koder-dekoder) za poboljšanje postojane vizualne kvalitete. Nadalje, u radu se predstavlja mehanizam za donošenje odluke o prekapčanju IVT temeljen na pokazivaču vremena isticanja veze i pokazivaču snage primljenog signala koji može smanjiti broj prekapčanja izborom stabilne staze. Provedena je opsežna simulacija kako bi se pokazala učinkovitost predloženih mehanizama.

Vehicular ad hoc networks (VANETs) are gaining tremendous interest among researchers and industries. Although the main reason for developing VANETs is traffic safety, many applications such as traffic status monitoring, road traffic management, routing and distribution of data, have emerged. VANETs exploit multi-hop communications among vehicles to deliver data packets. However, with fast mobility and intermittent link connectivity between vehicles, efficient and reliable routing in VANETs is becoming a challenging task. In order to make routing protocols robust to frequent communication disruptions and aware of unstable traffic and network conditions, several new routing metrics have been integrated with routing protocols. Such protocols are called traffic aware routing (TAR) protocols as their routing decisions are influenced by traffic and network status. The goal of this paper is to review the most recent traffic aware routing protocols while emphasising on traffic and network conditions awareness issues. In addition, this review investigated TAR protocols capabilities and limitations in terms of routing process, routing metrics measurement, forwarding mechanisms and recovery techniques. Moreover, challenges, critical issues and open research problems were discussed in the "Challenges and issues to consider" sections.
